Application filed September 27, lees. Serial No. 519,896.

To all whom it may concern: i

Be it known that I, DWIGHT FARNUM, a citizen of the United States, and a resident of the city and county of Denver and the State of 'Colorado, have invented a new and useful Advertising Device,of which the fol lowing, together with the accompanylng drawings, constitute a full, clear, and" exact specification, such as will enable any one skilled in the art to which it appertains to make and use the same. l

This invention relates to advertisingdevices and its object is to provide a novel sign, with novel means for attractingthe at-' tention, of passersby to the same, -through motion to actuate certainsound-producing.

Referring to the draw ngs, Figure 1, 1s a sition; Figs. 2 and 3 are respectively a plan vlew and a front elevatlon of the same; and Fig. 4:, 1s a diagram .of the form of a sheet of metal used in making thebody or frame for this device, the said sheet being bent into shape on the dotted lines. Fig. i is drawn to a reduced scale.

The shaft (6),upon which is mounted a helicoidal vane or blade (7), has its ends pivoted'in (1 1) and (15),. and vane (7) is so placed that the sides (1) L and (1 of the housing, form, each a de:

The exposed portions 00 y .2 m are constantly changing and are made up of consecutive, overlapping areas of the helicoid which give the effect of an infinite number ofpaddles mounted on shaft (6), thus making the transition of the consecutively exposed portions of the helicoid, into, and out of, the air-current, smooth and Without shock or jar. In whatever position the shaft (6) may have come to rest from previous rotations, the vane is at all times in equally advantageous positions to be set in motion by very slight currents of air.

The outer surfaces of deflectors (1) and (1 are to be utilized for signs, as shown, and other suitable surfaces may be variously disposed around this device for providing further advertising space. An example of the latter is shown at (20). In order that the signs may at the same time be seen from the front and from each side of the device, as well as from all intermediate directions, the signs may be set at suitable angles as represented by surfaces (32) and (33). The advertising surfaces may all be rigidly connected to, or form parts of the structure (1) or they may be composed of removable sheets (20), to be inserted in suitable holders (22) and to be fastened therein by screws (23) or other suitable means.

The various parts of this device, and espe cially the moving helicoid, are to be painted in different bright colors, or suitable combinations of such colors, in order to make the device conspicuous and attractive to the eye.

If it is so desired, the sound-producing feature may be left out of this device altogether and the moving helicoid be alone de- A pended upon to attract the desired attention to the same and to the advertisements which may be attached thereto.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
